Testing the MOSFIRE wavelength solution: comparison of arc lamp wavelength solution to sky lines

Tuan Do

In order to determine the accuracy of the MOSFIRE wavelength solution, I compared the solution determined using Ne and Ar lamps with that of the expected positions of OH lines.  This experiment tests a specific night and configuration, so is not meant to be comprehensive.

The dataset comes from observations of the Galactic center on 2012-05-29 and were reduced with an unofficial development version of the MOSFIRE pipeline that was modified to use the arcs to compute the wavelength solution.
